(2): compressor with integrated dryer
Fuse calculations for IEC
are done according to 60364-4-43 low-voltage electrical installations, part 4-43:
protection against overcurrent. Fuse sizes are calculated in order to protect the cable against short circuit.
Fuse type aM is recommended for fixed speed units. Fuse type gL/gG is also allowed and mandatory for
variable speed units.
Fuse calculations for cUL and UL
: The indicated fuse size is the maximum fuse size in order to protect
the motor against short circuit. For cUL fuse HRC form II, for UL fuse class RK5.
Possible configurations
There are 3 possible cabling layouts:
